Objective:This study aims to investigate the differences in hemostatic efficacy and patient comfort between an innovative domestically produced biodegradable nasal packing sponge and a traditional absorbent sponge following endoscopic nasal surgery. Methods:A prospective, randomized controlled trial design was utilized, including 30 patients who were divided into two groups according to random allocation, each receiving one of the two types of nasal packing. The study assessed the hemostatic efficacy, comfort, and safety of the materials by comparing the rates of no bleeding within 24 hours after packing, re-bleeding rates after 48 hours, pain ratings in the head and nasal areas, scores on a visual analog scale for nasal ocular symptoms, and safety indicators between the two groups. Results:The rates of no bleeding within 24 hours post-packing were 73.33% for both the experimental and control groups, with a no-bleeding rate of 100% after 48 hours in both groups. The pain rating in the head and nasal areas at various times post-packing was Grade Ⅰ（100%） in both groups, with no statistically significant difference（P=1.000）. The experimental groups sneezing score on the day of packing was（0.73±1.03）, lower than the control groups（2.27±1.67）, （P=0.007）; after 48 hours, the experimental groups sneezing score was（0.67±0.98）, also lower than the control groups（1.67±1.18）, （P=0.019）. There was no significant difference between the two groups in the Lund-Kennedy scoring during endoscopic examinations at the screening period, 7 days, 1 month, and 3 months post-packing（P>0.05）. Laboratory tests for other examination indicators were normal in both groups. Conclusion:The innovative domestically produced biodegradable nasal packing sponge not only provides hemostatic efficacy comparable to imported materials but also significantly improves patient comfort after surgery. It represents an economical and effective choice for nasal packing materials.

Objective:To analysis of the latent profiles and influencing factors of body image in patients with postoperative oral cancer.Methods:From July 2024 to March 2025, a total of 332 patients with primary oral cancer confirmed by pathology, aged ≥18 years, and undergoing oral cancer surgery at Hunan Cancer Hospital were selected using simple random sampling and cluster sampling. Among them, 25 were female and 307 were male. The body image scale and the Rosenberg self-esteem scale were used to investigate the patients. The main indicators included the total scale scores and scores on various dimensions of body image, such as appearance evaluation and health focus, with particular attention to satisfaction with facial appearance and oral function.The correlation between self-esteem and body image was analyzed, and differences in scores were compared based on gender, age, self-esteem level, and surgical procedure.Results:Among the 332 patients, 93.4% (310/332) were married, and 6.6% (22/332) were unmarried, divorced, or widowed. A total of 84.3% (280/332) underwent flap transplantation surgery, while 15.7% (52/332) did not. The body image distress in the 332 patients could be categorized into a body image adaptation group [80.12% (266/332)] and a body image disorder group [19.88% (66/332)]. Unmarried/divorced/widowed status ( P=0.020), undergoing flap transplantation ( P=0.006), and self-esteem level ( P<0.001) were identified as influencing factors for postoperative body image disorder in oral cancer patients. Conclusions:Given the varying levels of body image concerns among oral cancer patients, healthcare providers can implement targeted, personalized nursing interventions based on their distinct categories and influencing factors.

ObjectiveTo investigate the relationship between Jiaotai pill (JTP), its main component berberine (BBR), and the serotonin (5-HT) system in regulating islet hormone secretion and alleviating pancreatic β-cell dysfunction during type 2 diabetes mellitus (T2DM) progression.MethodsT2DM rat model was established using a high-fat diet and streptozotocin injection. JTP, BBR, and Metformin were intragastrically administered for 35 days. The analyzed indices included blood glucose, blood lipids, islet hormones, and proteins related to 5-HT synthesis, secretion, and transport. Additionally, an in vitro model of glucose injury in islet cells was established to study the effects of JTP and BBR on islet hormone secretion following tryptophan hydroxylase 1 (TPH1) inhibition.ResultsJTP and BBR significantly improved blood glucose and lipid levels and islet morphology in T2DM rats. Both models exhibited reduced islet 5-HT levels and impaired islet hormone secretion. However, the administration of JTP and BBR reversed these effects. Furthermore, JTP and BBR upregulated the expression of TPH1(P = .0194, P = .0413) transglutaminase 2 (TGase2; P = .0492, P = .0349), serotonin transporter (SERT, P = .0090), and 5- hydroxytryptamine 1F receptor (5-HT1FR) in the islet 5-HT pathway (P = .0194). In the cell model, the regulatory effects of JTP and BBR on islet hormone levels were significantly weakened after TPH1 inhibition (P = .001), suggesting that JTP and BBR influence islet hormone secretion through the pancreatic 5-HT system.ConclusionThe islet 5-HT system is correlated with islet hormone secretion dysfunction in T2DM. JTP and BBR can improve islet hormone secretion by activating the TPH1/TGase2/SERT/5-HT1FR pathway in the islet 5-HT system in T2DM rats.

Objective To investigate the therapeutic effects of Jiaotai Pill(JTP)on type 2 diabetic(T2DM)rats,a systemic study was conducted by examining the changes in neurotransmitter levels related to the hypothalamic-pituitary-adrenal(HPA)axis.Methods The rats were divided into a normal group,a model group,a metformin group(183 mg·kg-1·d-1),and a JTP treatment group(3.3 g·kg-1·d-1).A T2DM model was established using a high-fat diet combined with streptozotocin.After 28 days of intragastric administration of JTP and metformin,metabolic indicators,Fasting blood glucose(FBG),insulin(INS),blood lipids,and pathological changes in the liver and kidneys were measured in each group of rats.Levels of eight neurotransmitters were quantified in serum,urine,and multiple tissues(brain,heart,liver,kidney,intestine,and adrenal gland)using ultra-high-performance liquid chromatography-tandem mass spectrometry.Results Compared to the T2DM model group,the JTP intervention groups showed varying degrees of reduction in water intake,food intake,FBG,INS,and blood lipids(P<0.05).Additionally,the fatty degeneration in the liver,glomerular lesions in the kidneys,and dyslipidemia were significantly improved.JTP intervention significantly modulated the disordered neurotransmitter levels in the blood,urine,and various tissues of T2DM rats(P<0.05),with the greatest number of neurotransmitters showing a notable recovery in blood,urine,brain,and adrenal gland.Conclusion JTP at a dosage of 3.3 g·kg-1·d-1 can improve the glucose and lipid metabolism in rats.JTP can regulate the HPA axis-related neurotransmitter system,mitigating metabolic disturbances and organ damage associated with T2DM.

The adverse effects of fine particulate matter (PM 2.5) on human health have become a major global public health concern. Pregnant women and fetuses, as susceptible populations, are more vulnerable to the threat of PM 2.5 pollution. Increasing studies indicate that PM 2.5 exposure is an important risk factor of fetal growth restriction (FGR), and oxidative stress, inflammatory response, endocrine disorders, epigenetic modifications, autophagic abnormalities, and gut microbiota dysbiosis may be the biological mechanisms underlying PM 2.5-induced FGR. This study offers insights for the development of targeted preventive and therapeutic methods for FGR caused by PM 2.5.

Objective:To analyze the differentially expressed genes and related functional pathways of mouse sciatic nerves of Schwann cells(SCs)in early in vitro Wallerian degeneration(WD).Methods:The sciatic nerves of adult male C57BL/6J mice were Wallerian degeneration in vitro,and total RNA was extracted and transcriptome sequencing was performed at 3 h and 6 h after degeneration,respectively.The differentially expressed genes(DEGs),gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment were analyzed by bioinformatics.Results:Compared with the Control group,3961 and 5538 DEGs were screened in the WD 3 h group(WD3h)and the 6 h group(WD6h)of in vitro,respectively.The most significantly up-regulated genes mainly included molecules related to inflammation and immunity and neurotrophic factors.GO analysis showed that DEGs in both groups were enriched in positive transcriptional regulation and metabolic processes.KEGG pathway enrichment analysis revealed that DEGs were mainly concentrated in TNF signaling pathway,MAPK signaling pathway and ribosome production.Conclusion:At the early stage of WD,SCs up-regulates the genes related to inflammation and immunity to promote the progression of WD and secrete neurotrophic factors to support the survival of neurons,accompanied by the activation of TNF signaling path-way and MAPK signaling pathway.

Hepatocellular carcinoma(HCC)is the sixth most common malignant tumor in the world,accounting for 75%-85%.Due to the high incidence,strong heterogeneity and poor prognosis of HCC,early monitoring and fine assessment of high-risk populations are particularly important.In recent years,as a non-invasive method,radiomics has been widely used in the diagnosis,pathological characterization,selection of treatment methods and evaluation of curative effect of HCC.In addition,radiomics combined with next-generation sequencing technology and other multi-omics methods provide new ideas for HCC research.This paper reviews the research progress of radiomics combined with multi-omics in the field of HCC,in order to provide a new perspective for the diagnosis and treatment of HCC.
